A few months ago an unauthorized refrigerator and a couple microwaves were removed from a more or less common area on our floor here at work. Ever since then rumors have circulated that building management was going to conduct an office audit to see what other devices might be sucking electricity without the blessings of management. Apparently the rumors have become more substantial because the last few days have seen a lot of hand cart action as dorm-type fridges and microwaves make their way from offices to individuals' cars in the parking lot. The powers that be had better actually conduct the audit or there are going to be a lot of folks really annoyed at having removed something for apparently no reason.
Personally, I think a good solution would be to give this building an additional break room -- a couple more microwaves and another full-size refrigerator in a common area would remove some of the incentive for people bringing in their own appliances -- but that's never going to happen when there's a shortage of office space now.
